Simpe interest rate = PRT/100
— ( principal x rate x time ) / 100
$3,000 is the principal
3 years is the time
2% is the rate
so, PRT/100
(3,000 x 3 x 2) / 100
= $180
Answer : $180
Answer:
D. 2
Step-by-step explanation:
Common denominator is already presented which is 4.
-3/4 and 3/4 cancel each other out.
you can also convert to decimal form -3/4 + 2 3/4 is the same as:
-0.75 + 2.75 = 2.
Answer:L=x-1
Step-by-step explanation:
Perimeter of rectangle
=2(L+B)
P=10x-6
10x-6= 2(4x-2)+L)
Open the brackets
10x-6=8x-4+2L
Collect like terms
10x-8x=-4+6+2L
2x=2+2L
2x-2=2L
Divide through by 2
L=x-1
Length of the rectangle is L=x-1
If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to
... (x +3)² = 0
This multiplies out to give
... x² +6x +9 = 0
The value of m is 6.
_____
For finding the square of a binomial, you can either use the special form you have memorized:
... (x +a)² + x² +2ax + a²
or you can use the distributive property.
... (x +a)² = x(x +a) +a(x +a)
... = x² +ax +ax +a² = x² +2ax +a²
The function of f(x)=-x+4x-3 is 3x-3. I hope this helps. :)
